Working principle: when a sample needs to be sent into the mass spectrometer, the sealing cover 3 is opened, a worker places the sample above the receiving plate 101, then covers the sealing cover 3, then vacuumizes the inside of the shell 1 through external control, moves the receiving plate 101 to one side close to the sample sending plate 4 through the pushing mechanism, places the sample above the sample sending plate 4, sends the sample above the sample sending plate 4 into the mass spectrometer through the sample sending mechanism, and ionizes and analyzes the sample by an ion source of the mass spectrometer, so that the design can ensure that the sample is always in a vacuum state when entering and exiting, improves the vacuum safety of the sample when entering and exiting, and facilitates normal use of the mass spectrometer; in the initial state, the baffle plate 8 is in a closed state, namely the sample feeding groove 201 is closed, at the moment, the whole shell 1 can be divided into two parts under the action of the baffle plate 8 and the partition plate 2, one part is the receiving plate 101, and the other part is the sample feeding plate 4; when the closed cover 3 is not opened, two parts of the shell 1 are in a vacuum state, when the closed cover 3 is opened and the position of the baffle plate 8 is unchanged, one side of the sample feeding plate 4 is still in a vacuum state, when a sample is placed above the receiving plate 101, and the closed cover 3 is closed, and when the interior of the shell 1 is vacuumized, only one side of the receiving plate 101 needs to be vacuumized at the moment;
then the cylinder 5 is controlled to move, the telescopic end of the cylinder 5 drives the pushing frame 501 to move towards the side close to the baffle plate 8, the pushing frame 501 pulls the elastic pull rope 6 above the pushing frame 501 when moving, so that the elastic pull rope 6 pulls the baffle plate 8 at the other end of the elastic pull rope through the fixed pulley block 7, namely, the baffle plate 8 moves upwards, the baffle plate 8 is gradually prevented from obstructing the sample feeding groove 201, then the receiving plate 101 can enter the sample feeding plate 4 side through the sample feeding groove 201, and then a sample can be fed to an ion source of a mass spectrometer through the sample feeding mechanism, so that the design can ensure that the sample is always in a vacuum state during sample feeding, the detection position is always in vacuum, the shell 1 is divided into two parts, and only half of the shell 1 is required to be vacuumized each time, so that the energy loss is reduced; when the sample is required to be taken out after the detection is finished once, the receiving plate 101 is positioned at one side of the sample conveying plate 4, the sample conveying plate 4 conveys the sample to the upper side of the sample conveying plate 101, then the telescopic end of the air cylinder 5 is controlled to drive the pushing frame 501 to recover, the pushing frame 501 and the receiving plate 101 firstly pass through the sample conveying groove 201, at the moment, the elastic pull rope 6 at one side of the pushing frame 501 is not pulled any more, namely the baffle plate 8 is not pulled any more, so that the baffle plate 8 slowly moves downwards along the limiting groove 9, and when the pushing frame 501 and the receiving plate 101 completely pass through the sample conveying groove 201, the baffle plate 8 can block the sample conveying groove 201 again, further the subsequent sample feeding is facilitated, and the design is adopted, so that the samples in and out can be ensured to be in a vacuum state all the time;
when a sample is sent to one side of the sample sending plate 4, the electric pull rod 14 in the guide plate 12 is controlled to move, so that the telescopic end of the electric pull rod 14 drives the conveying plate 13 and the sample sending plate 4 to move upwards, the sample above the sample sending plate 4 is sent to one side of the ion source of the mass spectrometer, and the receiving plate 101 only needs to control the electric pull rod 14, the conveying plate 13 and the sample sending plate 4 to move upwards when the receiving plate 101 moves to one side of the sample sending plate 4 because the horizontal height of the sample sending plate 4 is smaller than the horizontal height of the receiving plate 101; when the sample feeding plate 4 moves downwards after one-time detection is finished, and the sample feeding plate 4 moves to a position lower than the bearing plate 101, the detected sample is directly positioned above the bearing plate 101, so that the subsequent bearing plate 101 can conveniently take out the sample, and the design is convenient for the sample feeding and discharging to be always in a vacuum state, and the sample feeding and taking out can be ensured; when the receiving plate 101 is restored to the initial position again, the first contact 801 and the second contact 16 are not contacted, the telescopic end of the control cylinder 5 drives the receiving plate 101 to move towards the side far away from the sample feeding groove 201, namely the baffle plate 8 is enabled to move downwards into the rectangular groove 15, the first contact 801 and the second contact 16 at the bottom of the baffle plate 8 are enabled to be in contact with each other, and under the contact of the first contact 801 and the second contact 16, external control is opened, so that the control motor is enabled to control the electric pull rod 14 and the guide plate 12 to move downwards, the follow-up conveying of other samples is facilitated, and due to the design, the control element can be ensured to be in a vacuum environment, and the sample feeding safety is improved.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
